DEVICE FOR CUTTING VEHICLE-AXLES.

SPECIFICATION forming part of Letters Patent No. 368,178, dated August 9, 1887.

Application filed February 17, IESS. Renewed July 19, 1887. Serial No. 2111.721. (No model.)

To aZZ whom it may concern.:

Be it known that I, OSCAR VIHTHORE, a resident of Oakland, county of Alameda, State of California, have invented a new and useful Machine for Cutting Vehicle-Axles; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings.

My invention relates to a machine for turning and cutting the arm ofan axle ofa wagon or other vehicle, and thereby adjusting the same to the worn box and obviating the use of washers.

The following description fully explains the nature of my said invention and the manner in which I proceed to construct, apply, and operate the same, the accompanying drawings being` referred to by figures and letters.

Figure l is a perspective view of the machine, showing it attached to an axle. Fig. 2 is a horizontal longitudinal section of thcsamc, showing the supporting-plate for the cutterhar, the chambers holding the clamps and the right-and-left-hand screws, the sleeves in said chambers, the eutteigbar and crank, and the knife and the adjusting-screw. Fig. 3 is a vertical section on the lincy/ y, Fig. 2, showing the inner chamber and sleeve, a right-and-lefthand screw, and set-screws for a pai r of clamps. Fig. 4 is a vertical section on the liuezz, Fig. 2, showing the outer chamber holding thesame. Fig. 5 is a front elevation showing the knife and the manner of attaching the adjustingscrew thereto.

My improved machine A, for cutting axles, consists of the following parts or elements: A rear supporti iig-plate for the cutter-bar, having a downwardly-extending lug on each side, two boxes or chambers, each having a sleeve or bearing; a pair of clamps through which extends a right-and-lreft hand screw and a pair of set-screws, a cutter-bar provided with a crank, and a knife placed between guide-blocks.

Referring to Figs. 1, 2, the lugs b of the rear supporting-plate, Z1', are bolted to the cutter-bar c, and at the head of said bar arebolted guide-blocks d d', between which the knife e is placed. An adjusting screw, q, passes through a lug, j, on the head of the cutter-bar, and is attached to the knife in the T- shaped slot e, Fig. 5. The cutter-bar isprovided with a crank, e', by which the cutter-bar is turned in the operation of cutting. rlhe outer chamber Z,havi ng aplate and slceve,i, which pass through the hole in the cutter-bar, is attached to the inner chamber, 7;, by screws and contains in the upper or forward section a pair of clamps, a, through which and both walls of the chamber extends below the centcra rightand-lefthand screw, p, one end of which is squared for the action of a wrench. The object of these clamps is to center the axle and hold it rigid. On each side of the chamber there is a set-screw, s, which is set against the side of the clamp to hold the axle fixed and rigid. The plate and sleeve 'i of chamber Z is attached by screws a to the sides of said chamber, Figs. 2, 4. The inner chamber, 7s, is covered by a plate, o, and has a sleeve, h, which extends to chamber Z, and also contains in the upper or forward section a pair of clamps, m, through which and both walls of the chamber extends above the center a right-and-left-hand screw, o, one end of which is squared for the action of a wrench. On each side ofthe chamber there is aset-screw, o', which is set against the side of the clamp to hold it to the axle in a rigid manner. 30th chambers Zh are attached by screws t, Fig. 2.

rIhe axle may be centered by a single pair of clamps; but I prefer the joint action of two pairs and employ them in my machine, and while a good bearing for the axle may be obtained by a single sleeve I preferably employ two, onein cach chamber, as shown in Fig. 2.

The machine is set by slipping the axle into the sleeves orbearings and through both chambers, and both pairs of clamps are centered upon and grip the axle by the action of the right-aud-left-hand screws, which are set by a wrench. The set-screws are then adjusted to the sides of the clamps, which they hold rigidly to the axle. VVheu the axle is set to the required gage for cutting, the cuttcr-barholding the knife is turned, by which action ashaving is cutoff the axle. After each cut the knife is adjusted to the axle by the adj usting-screw, and this operation is repeated until the cut is completed.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
